The file provides a picture of the air quality with regard to particulate matter around national, provincial and municipal roads in Gelderland for the year 2021. The data has been calculated nationally using the reporting tool. The concentration at 10 meters from the edge of the road is indicated for each road section. The air quality is presented in five concentration classes. The average annual concentration of PM10 is shown in the legend. According to the standards, the annual average concentration may not exceed 40 µg/m3. The World Health Organization (WHO) recommends 20 µg/m3 as a safe standard according to the latest scientific insights. The air quality is calculated, among other things, on the basis of traffic counts and calculation models. The sources, such as industry and agriculture, are included in the background concentration. The direct contribution from road traffic is also included in the total concentration. The values ​​calculated with the model have an inaccuracy of 20-25 percent.
